MySQL de Bash

Definir Alias

set alias sugar = 'mysql --default-character-set=utf8 -u sugar -psugar -B sugar -h localhost '

Ejecutar consulta

echo "SELECT user_name FROM users WHERE is_admin = 1;" | sugar

Listado de Tablas

set alias tablas='echo "show tables" | sugar | grep -v Tables_in | sort -u'

Listado Tabla Campo

set alias tablacampo='echo "show tables" | sugar | grep -v Tables_in | while read t; \
do d=$(echo "desc "$t";" | cct15 | grep -v Field | awk1); \
for c in $d;do echo $t"__"$c;done ;done'

Quitar nombre de campo

mysql -N

Vaciar todas las tablas que contengan la palabra calls

sugar < $(echo "show tables" | sugar | grep calls | while read t;do echo "TRUNCATE table $t;";done)

MySQL desde Vim

Agregar en .vimrc

command -range=% SUGAR :<line1>,<line2>w !mysql -u sugar -psugar -B sugar -t -v -v -v

Ejecutar todo el archivo

:SUGAR

Ejecutar la línea actual

:. SUGAR

Ejecutar un rango de líneas

:3,8 SUGAR

Ejecutar desde línea actual hasta el final

:.,$ SUGAR

Usar diccionarios

:set dictionary=tablas, tablacampo

CTRL-X CTRL-K

Reemplazar Texto

Traducir valores

SELECT      REPLACE(REPLACE(direction,'Inbound','Entrante'),'Outbound','Saliente') AS direccion
FROM        calls;

Actualizar registros

UPDATE contacts SET last_name = REPLACE(last_name, 'NUNEZ', 'NUÑEZ');

Buscar duplicados

SELECT      last_name, first_name, COUNT(id) AS total
FROM        contacts
GROUP BY    first_name, last_name
HAVING      total > 1
ORDER BY    last_name, first_name;

Agrupar

SELECT      name,
            (
            SELECT  CASE
            WHEN    EXTRACT(HOUR FROM date_start) < 12
            THEN    'mañana'
            ELSE    'tarde'
            END
            ) AS turno,
            COUNT(id) as total
FROM        calls
GROUP BY    name, turno
HAVING      total > 500
ORDER BY    total DESC;

Cruzando tablas

Explicito mejor que implicito

SELECT      COUNT(cc.id) AS total
FROM        calls_contacts cc
LEFT JOIN   contacts co ON co.id = cc.contact_id ;
AND         cc.deleted = 0
AND         co.deleted = 0

SELECT      COUNT(cc.id) AS total
FROM        calls_contacts cc, contacts co
WHERE       co.deleted = 0
AND         co.id = cc.contact_id
AND         cc.deleted = 0

Contactos con llamadas

SELECT      COUNT(cc.id) AS total
FROM        calls_contacts cc
LEFT JOIN   contacts co ON co.id = cc.contact_id;

Contactos con llamadas entrantes

SELECT      co.last_name,
            co.first_name,
            CONVERT_TZ(date_start, '+00:00', '-03:00') as fecha
FROM        contacts co
INNER JOIN  calls_contacts cc ON (cc.contact_id = co.id AND cc.deleted = 0)
INNER JOIN  calls ca ON (ca.id = cc.call_id AND ca.deleted = 0)
WHERE       co.deleted = 0
AND         last_name IS NOT NULL
LIMIT       20;

Actualizar las llamadas de un contacto

UPDATE      calls ca, contacts co, calls_contacts cc
SET         ca.assigned_user_id = (
                                    SELECT  id
                                    FROM    users
                                    WHERE   user_name = 'osiris'
                                    )
WHERE       ca.id = cc.call_id
AND         co.id = cc.contact_id
AND         co.id = '2a756d50-ae20-0754-a7c7-49beb64cee37';


UPDATE      calls ca
INNER JOIN  calls_contacts cc ON cc.call_id = ca.id
INNER JOIN  contacts co ON co.id = cc.contact_id
SET         ca.assigned_user_id = (
                                    SELECT  id
                                    FROM    users
                                    WHERE   user_name = 'osiris'
                                    )
WHERE       co. = '2a756d50-ae20-0754-a7c7-49beb64cee37';
